Welcome to the sub!

Side note first: I'm focusing this advice towards communication between men and women, as I think same sex couples do not struggle with this to the same extent.

This seems to be the first biggest question: Should I reveal that I'm a cuck on a dating profile?

Unless it's a sexual dating community here on reddit, or on Fetlife, it's probably best to NOT use the word cuckold. If you're an excellent writer and/or above average in attractiveness, then possibly use the word on Feeld or even Okcupid, but you'll have to be quite the wordsmith.

For the other non-kink apps, don't.

The next question: Should I use a less directly fetish description on a profile? I've been experimenting with this, and it's tough. My example is to say what Cuckoldress Vixen recently suggested on an interview: I'm interested in a one-sided open relationship where you have all the freedom, and we both love it that way.

Other indirect versions of reveal on a profile can be used. I've tried several, but it does reduce the matches you will get.

A big downfall of that is, that some women that are actually willing to cuckold a guy later on, are put off by the reveal of a sexual desire on a profile. This might account for more potential matches than we realize. I've seen more than one woman on r/BDSMadvice say that she would pass on such a profile even though she is into that kind, and an ex of mines says the same thing. She's open to theesomes later in a relationship, but wold not match with a guy that reveals anything on his profile.

This might be a no-brainer for some people, but others of us struggle really really hard with not being able to use our profile as a filter.

It is possible that Vixen's recommendation of mentioning "one-sided open relationship" is not a phrase that will turn too man women away that are also interested in such things.

Didn't reveal it on your profile?

So, then when do you mention it if you didn't reveal on a profile, or you met her in person?

Mistress Nurture on YouTube recommends to mention it on the 2nd or 3rd date. Still, do not use the cuckolding label, but ask her, in your own way, if she knew her partner would stay with her and support her, would she like to be able explore extra sexual freedom. This is only after checking for a personality match and chemistry on the 1st date.

Best of luck to you! This post will be updated. I know it is such a challenge to make these early decisions on dating profiles, and also then when to admit it in person for those that wait.
